Title Double Pulse Solid Rocket Motor Design
Abstract
In the 1950's, the solid rocket breakthrough a lot in the technical field , and the solid rocket motor are widely used in ballistic missiles and launch vehicles. In the 1960's, the foreign countries made a great mass of works in theoretical and experimental studies of controllable thrust solid rocket motor to explore a lot of technical approaches and designs. Solid rocket motor with the advantage of security, reliability, and storage performance density than the ascribed and service processing advantages of convenience, it become a major power plant in the strategic field of tactical missiles weapons. Pulse solid rocket motor is a new type of solid rocket motor which risen in the late 20th century, its propulsion system development has opened a new direction of development, have potential applications in the aerospace and military fields. This paper mainly studies the dual-pulse rocket engine general structure, propellant structure design, the combustion chamber design, nozzle design, the ignition system design and interior ballistic calculation. The purpose of designing dual-pulse solid rocket motor is to understand the structure and key technology of dual-pulse solid rocket motor, and lay a solid foundation for the development of high-performance solid rocket motor.
